There is nothing wrong with those balls. I like the idea SVstar34 stated with getting the Scorchin' Inferno and the Wrath XP redrilled (and resurfaced with oil extraction) as a starting point. Once you get back into the game, you can continue getting previous balls reconditioned one at a time.
If you are bowling on THS most of the time, you won't see too much of a difference between your current equipment and newer equipment.
